Golden Chao egg
Go to the Station Square area. Then, go to the area when you fought Chaos for the first time. Look to the side of the City Hall entrance to find an egg shaped rock. Take the rock to the building to the left from City Hall. Walk to the window to see a golden Chao egg. However, if you try to take it the front door will lock. Replace the egg with the rock and the door will unlock, allowing you to leave with the egg. When the egg hatches, a golden Chao will be born.
